"Comportamiento al impacto de barreras sostenibles para seguridad vehicular provenientes de llantas usadas con respecto a un sistema convencional de barreras"

The following project aims to analyze the impact behavior of the system of sustainable barriers for vehicular safety from used tires using the finite element method (MEF), using computer software applied in Mechanical Engineering. This issue is raised by the large number of vehicle accidents that exist due to speeding against the conventional system of protection on roads that do not adequately fulfill the function of reducing the impact when vehicles deviate from the road, resulting in losses Material and human. In this way, it is sought to facilitate the knowledge of the behavior of these passive safety elements that allow cushioning the impact and together with this system redirect the vehicle to the road, in turn reduce environmental pollution by taking advantage of the tire as raw material. To carry out the realization of the proposed theme, the three-dimensional (3D) computer-assisted modeling tools are integrated, such as the SolidWorks program, with which the elements of the system of sustainable barriers will be designed, the respective simulation between the object and the system of barriers through the study of impact, which allows, with the analysis of results to observe the behavior of the effects that will be caused in the components of the mentioned system. In addition, the proposal aims to attract the attention of citizens, to reuse tire waste in an appropriate way generating benefits for society and to drive responsibly, at the established speed. The system will have separators that were designed under the INEN - 2473: 2013 standard that were coupled to the rotating barrels, through the design and mechanical application software ANSYS ACADEMIC R3, the phases of the sketching were performed, generating the meshing whose conditions of impact speed was 75 km / h, 90 km / h and 110 km / h, established impact time of 0.2 sg, a curve of 2500 m, angle of impact 20 ° and movement restrictions, given these values a total deformation was obtained of the 0.30 m barrel, the restriction of movement (post) exceeds the breaking limit being 757 MPa causing the permanent breakage of the element and 0.16 m of plastic deformation, said study has a final cost of $ 987.98 being this the best alternative for the development of sustainable barriers.
